Abstract:

Rice is a critical staple eaten in almost half of the world but problems leoniloarise due to climate change. An interdisciplinary approach to tap the potential of 16,000 rice collection have led towards revealing potential parent lines that could help in increasing rice production. This paper aims to present the results of the evaluation of rice germplasm conserved in the genebank. Seven hundred ninety-four accessions were resistant and 883 as intermediate to rice blast, 317 intermediate to bacterial leaf blight, 27 intermediate to sheath blight, two accessions were resistant and six accessions were intermediate against tungro. On one hand, 27 had potential drought tolerance while 5 accessions were tolerant to zinc deficiency, 11 tolerant and 5 moderately tolerance to salinity stress, four tolerant and 14 moderately tolerant to submergence stress. The result of the evaluation can serve as guide for breeders in choosing the parent materials for breeding of new rice lines/varieties that could accommodate the need of farmers for resistant/tolerant varieties against major rice diseases.
